ConclusionsConclusionsSP-1 SP-2

Both soils show signs of illuviation and eluviation.SP-1 is a much younger soil composed offloodplain deposits (transported), while SP-2 isa much older soil formed from weathered bedrockon a ridge scraped clean by glaciers (formed inplace). SP-2 shows well defined horizons while SP-1 has poorly defined horizons.
